Continuation in part of application Serial No. 732,809, filed November 22, 1912. This application filed.

Serial No. 800,062.

To all whom it may concern Be it known that I, HENRY F. HAGE- MEYER, a citizen of the United States of America, residing at Toledo, Lucas county, ()hio, have invented a new and useful Burner, of which the following is a specification.

This invention relates to the propagation of combustion, especially at a high velocity.

This invention has utility when embodied in fluid burners, particularly for local heatings of considerable intensity.

Referring to the drawings: Figure 1 is a perspective view of an embodiment of the invention in a burner for gaseous fuel; Fig. 2 is a transverse section, on an enlarged scale, through the burner body; Fig. 3 is a fragmentary view of one half of the burner body on the line IIIIH, Fig. 2, the lower channel member being omitted; Fig. 4 is a section on the line IV-IV, Fig. 3; Fig. 5 is a section on the line V.-V, Fig. 3; Fig. 6 is a section on the line VTVT, Fig. 3; Fig. 7 is a medial longitudinal section through the fuel supply connections; and Fig. 8 is a medial longitudinal section through the fuel commingling chamber.

The commingled gaseous fuel from the duct 1 passes into the chamber 2 in the lower channel member 3 of the burner body. From this chamber 2 the fuel-supply passes through the openings 4 between the lugs 5 striking the baffle 6 in the chamber 7. Leading from the chamber 7 is the slot passage 8 of area slightly less than the aggregate area of the holes 1. This slot 8 leads to the chamber 9 having the slot passage 10 leading to the chamber 11, which has the primary fuel supply opening or slot 12. The area of the slot 12 is to advantage less than the area of the opening 10, and opening 10 is less than the area of the opening 8. This feature assists in stepping up the velocity of the fuel supply, while with the chamber volumes larger as the openings are smaller, notwithstanding the increased velocity, there is effective commingling. The series of chambers with the connecting passages insures uniform pressure distribution throughout the length of the primary fuel supply opening or burner slot 12. These chambers and passages are shown as formed between the burner body members 13, 14. These members 13. 11, are held snugly together at the bottom by the screws 15 (Fig. 6), while provision is made by the screws 16 (Fig. 4) for adjusting the upper spacing between these members 13, 14. Adjacent the spacing screws 16 are the clamping screws 17 insuring a firm locking of the members in ad usted position. The slight outward tilting is small but permits great refinement in adjusting the openings for fuel supply.

In assembling the members 13, let, they are lined up for the various screws by the dowel pins 18, which may extend through the auxiliary body members 19. The members 19 are clamped to the body members 13, 14, by the screws 20 (Fig. at). The needle valves 21 are adjustable to regulate the auxiliary fuel supply from the chamber 2 to the chamber 22, from which the fuel may flow through the passage 23 to the chamber 24, and thence via the slot passage 25 to thechamber 26 having the slot fuel supply opening 27 directed toward the main fuel supply slot 12. This auxiliary fuel supply from the opening 27 may to advantage operate as a less velocity envelop for the main fuel supply, thereby making possible greater velocity of burning at the main fuel supply opening 12. The enlargement 28 at the angle in the slot passage 27 precludes retarding of velocity at this point. Adjustment is permitted by the screws 29 (Fig. 5) so the passages may be closely regulated. The screws 20, serve to hold the tilted members 19 in the adjusted positions.

In some fuel mixtures it is desirable to supply additional air for better supporting combustion, and provision is made therefor from the supply line 30 having the valves 31 in the ducts 32 leading to the passages 33 in the members 13, 14:. These ducts 33 lead to the longitudinally extending chambers 34 having the discharge slots or openings 35 between the opening 12 and the openings 27. The volume and pressure of this supplemental air supply may be regulated as the occasion warrants.

The screws 36 by extending through slots 36 (Fig. 3) in the members 37 (Fig. 5) may serve to clamp the members 37 in adjusted positions adjacent the members 19 to provide chambers 38 supplied with fuel from the passage 27 by the openings 39. The

. fuel.

chambers 38 are connected by the passages 40 with the chambers 41 having the slot openings 42 directed toward the auxiliary openings 27 and main opening 12 the beads 40 (Fig. 3) on the members 37 serve to partially separate the chambers 38 from the chambers 41. As these beads 40 do not extend to the members 19 the passages 40 be tween said chambers are provided. Adjustment of the members 37 varies the openings. 42. There is accordingly provided two auxiliary fuel supply openings which may emit fuel at different velocities to form envelops for the main thin sheet of flame from the long narrow or line discharge opening.

The screws 43 (Fig. 1) serve to clamp the end closure plates 44 in position to thereby complete the chambers and passages longitudinally extending in the burner body.

The air supply line 45 may be controlled by the valve 46 having the nozzle 47 in the housing 48. The fuel supply or gas line 49 may be controlled by the valve 50 to supply fuel about the nozzle 47 in the housing 48.

- The velocity of the combustion supporting flow in the duct 52.

supply from the duct 45 in passing to the oppositely directed and somewhat larger reversely extending nozzle 51, draws in an en-' velop of fuel which is at once commingled in the expansion due to the enlargement of the passage 52. This reverse nozzle 51 may have its distance varied from the air nozzle 47, thereby permitting great nicety of adj ust-ment ofv fuel and air. This adjustment is effected through the bushing 58. While some -commingling is thus brought about, further agitation besides that effected in the burner body, may be caused by leading the duct 52 into' the chamber 54. Openings 55 from the duct 52 may be of such area as to care for thefuel supply at the velocity of These openings 55 direct the incomingfuel toward the walls of the chamber 54. From this chamber 54 the mixed .fuel passes into the duct 1 to the burner body.

The disclosure is a simple burner for producing high temperature results with cheap fuels. In action the burner is self cleaning.

. In structure it isaccessible for inspection or such adjustments as may be desired, even to varying the directed flame within the burner length.
